====== Example: Get the View Vector ====== This example demonstrates using the active ''View Vector'' of the viewer. When any view changes position or direction, you can retrieve that view's position using the ''getViewVector()'' function. The return value is a CoordinatePart with 3 coordinates : * The view position * A second position that, together with the view position, forms the forward vector * A third position that, together with the view position, forms the up vector
